I'm not sure that clustering goes beyond "multiple hosts with single API to rule them all" - thus I assume when physical node needs maintenance, it won't magically migrate / restart VEs on other cluster members. May be wrong here.
P.S. Microcloud tries to achieve this AFAIR, but it's from Canonical, so on LXD.
Okay then my question still stands. You are saying "similar to any other system which needs to reboot", but this is nowhere near similar to something like k8s, which has 1st class support for this. You cordon the node you are about to take off for maintenance, kubernetes automatically redistributes all the workloads to the other nodes, and after you are done you uncordon the node.
How does this look with Incus? Obviously if the workload you are running has some kind of multinode support you can use that, but I'm wondering if Incus a way to do this in some kind of generalized way like k8s?
But I did some more reading, there seems to be support for live migration for VMs, and limited live migration for containers. Moving stopped instances is supported for both VMs and containers.
